Roofing 101: Replace or Repair?
Homeowners who want to know when they must repair or replace their shingled roofs can benefit from this video, showing viewers signs that it’s time to replace a roof even if it is relatively young.
Over time, shingles become damaged. A common source of physical damage is hail that causes uniform, darkened indentations in shingles. However, dark spots on the roof may also be blisters that form when a poor ventilation system leads to overheating. Unlike hail hits, these spots are irregular, and the broken shingle will lift around the blister.
Both issues allow water to seep through the shingles and damage the structure underneath, which is known as decking. Preventing water damage to decking extends the life of a roof. Chimneys can cause leaks when the tar around the chimney cracks. If homeowners do not use a fireplace, they can request chimney removal to prevent leaks.
No roof lasts forever, however. In a temperate climate, roofs may last up to 30 years, but roofs in more extreme climates may only last 15 years as temperature fluctuations cause shingles to become brittle and break. Finally, poor installation or roof repairs can require repair or replacement in just five years.
